Renewable resources are ones that regenerate themselves, such as wind or solar power. Oil is a nonrenewable resource because there is a limited supply in the world. When burned, the sulfur in oil turns into compounds that cause acid rain.
Oil spills are both costly and deadly. Cleaning up an oil spill uses resources, and many animals in the area can be harmed by the spill. Animals can ingest the oil, and birds' feathers can become coated in oil, causing them to lose buoyancy.Learn more about Engine Oil
Synthetic oil may last anywhere from 5,000 to 7,000 miles before it needs to be changed, although some brands may last as long as 10,000, 15,000 or even 20,000 miles. Change interval length also depends on factors such as road conditions and trip mileage.Full Answer >
The main reason oil floats in water is because it is less dense than water. Anything less dense than water will float, including the human body, which contains fat, a chemically similar substance to oil.Full Answer >
Viscosity describes a fluid's resistance to flow. The thicker the fluid, the slower it flows and the higher its viscosity. The viscosity of a lubricant such as oil affects how it reduces friction and transfers heat.Full Answer >
Fracking, or hydraulic fracturing, is a way of artificially stimulating oil and gas wells by forcing pressurized water underground into fossil fuel reservoirs. This fractures rock formations in these pockets, helping bring more hydrocarbons to the surface. The practice can also affect groundwater and the seismic stability of a region.Full Answer >
